Webi Filters Automatically Changing Values

Hi experts,

I am experiencing a very strange issue in webi report filters, i have the following filters based on the Dimension variables

Filter One:    Company

Filter two:     Division

Filter third:   Quarter

Filter fourth: Voltage

When i select a value from Company Filter and then select any value from Division Filter it Automatically reset the Company Filter value to "All Values", same is happening for the other filters like if i select any value from quarter filter after selecting company and division value it resets the company and division values to "All Values" automatically.

Using a Bex Query via BICS connection.

Any Help ??

Thanks and best regards
